@ArrivedLeader22 This is just a guess but I think the reason as for why some people would be against making changes for an old civilisation is because they are also veteran players of [Age of Empires 2] as well.
If you are familiar with how some people behave from the [Age of Empires 2] community then there are those who won’t like it when someone suggests any kind of drastic change for the older content.
I remember giving a response to a post made by another user on the [Age of Empires 2] forum section who suggested that a unit named the “Traction Trebuchet” could be added to the game. But since the term is of modern origin I suggested instead that it would be better if it was given the name “Mangonel” since that is the historical name of this type of siege engine, and where the already existing in-game [Mangonel] could be renamed to [Catapult].
The only responses that I got from this comment that I made were people complaining, including from the OP as well, that it would be “Confusing” for the playerbase to give the name of an older unit to this new unit instead [which would be more appropriate] or answers like this:
The funny thing is that the user who came with the suggestion of adding the Traction trebuchet to the game is also active on the [Age of Empires 3] forum and have created their own threads for what changes can be made for this game. Even for the purpose of clearing up some historical inaccuracies that are present in the game.
There were also two other users on that thread that I know are active posters on the [Age of Empires 3] forum who chose to give likes to the comments that did not want this change.
